From f3894c9fa1904572ee21b5c3aa2ca9e26a5d5d1e Mon Sep 17 00:00:00 2001 From: Wade Walker Date: Mon, 11 Feb 2013 17:00:02 -0600 Subject: Make JarUtil work with custom classloaders Added the ability for users to set a "resolver" in JarUtil that lets it find resources that are loaded by a custom classloader. This is needed in OSGi apps (like Eclipse RCP apps), since OSGi resources do not have simple jar: URLs (they use a custom protocol called bundleresource:). --- src/java/com/jogamp/common/util/JarUtil.java | 24 +++++++++++++++++++++++- 1 file changed, 23 insertions(+), 1 deletion(-) (limited to 'src/java/com/jogamp/common/util/JarUtil.java') diff --git a/src/java/com/jogamp/common/util/JarUtil.java b/src/java/com/jogamp/common/util/JarUtil.java index 84ec59d..f1488f1 100644 --- a/src/java/com/jogamp/common/util/JarUtil.java +++ b/src/java/com/jogamp/common/util/JarUtil.java @@ -52,6 +52,26 @@ import jogamp.common.Debug; public class JarUtil { private static final boolean DEBUG = Debug.debug("JarUtil"); + /** + * This interface allows users to provide an URL resolver that will convert custom classloader + * URLs like Eclipse/OSGi "bundleresource:" URLs to normal "jar:" URLs.
